The type of material used to secure the device to the recipient's limb can vary depending on the type of device you are making.
The original style of gauntlet and bicep cuff has wide slots to accommodate a variety of sizes of velcro. This makes it easy to find materials and assemble the device, but can result in a poor or uncomfortable fit. The newer style of gauntlet and cuff have several, smaller slots that work with velcro cable straps. They may be harder to find in some areas, but they allow for a more precise fit.
For some types of devices (e.g. Osprey hand), you will use leather for securing the device. This offers many advantages, but is harder to assemble.
